E4OD-4R100 Valve body kits: Bulkpart transmission parts

I am wanting to start pulling about 10K pounds and want to protect my tranny.

Any ideas? I think the first one is the best?

Well I would avoid anything that is going to raise fluid pressure. That said you might want to try the c00nhunterjoe accumulator body mod. It doesn't cost anything but your time and I like what it did for my truck.

See these threads on this subject.

A rise in line can be a good thing. Just dont go nuts with it.
Its like adding pane. Small amount goes a long way.

OP
Really depends on if you are going to pull the pump or not.

The coon mod..... lol!

Transgo hd2 kit is the way to go, its safe, reliable, and very easy to work. I personally use it in my truck with a few extras from the gents at ATS
